direct air and duel exhaust...

First let me thank cabinfever for the idea of direct air...i put the finished product on my 50 slant...i dropped the neddle setting down a notch and with the air intake it has smoothed out my start and added to my top end by 2 mph...and its smooth...i took my large expansion pipe off and went with deul exhaust 13.95 plus shipping...smooth...ha...thanks...enjoy...Dennis

you are welcome,its all about trying new ideas out and to get a smoother running bike.
i origionally did this to relocate the airfilter since i didnt have room for one on my roadmaster sx sport(my last build) and it did so well that i kept using it on my new bike a scwhinn delmar cruiser even thou i now have room for a fullsize airfilter in stock location. I am looking to do a redesign on the pipe and filter for even more performance and i will be doing something to quiet down the clutch and cover. plus i need to clean out my muffler sometime(darn power robbing black cat muffs).

get rid of that black exhaust...cuts power down alot....as far as the sound from the clutch cover, i bought some of the krylon rubber paint and sprayed it in the inside of my covers...3 coats...works good...catch you later...Dennis

well i have two screen filters as you can see in the parts...and if it does happen it would give me an excuse to change it to a 80cc...by the way how did it perform while it was working...thank you...Dennis

Engines without airfilters will have very short life. With or without rocks going in, with or without screens..

I thought science told us "ram" air on relatively slow vehicles didn't have any effect.
